目的对北京市西城区在2011-2015年间,开展的男男性行为者(MSM)艾滋病病毒(HIV)咨询检测服务的现状进行评估。方法采用回顾性研究方法,收集2011-2015年西城区4个自愿咨询检测(VCT)点的HIV检测相关数据,利用描述性统计分析方法进行数据整理和统计分析。结果 2011-2015年,共为3 487人次MSM提供了VCT服务、HIV及梅毒检测,HIV阳性率为5.8%(203人次),梅毒阳性率为7.6%(265人次)。HIV感染者中95.1%(193/203)接受了CD4~+T淋巴细胞(简称CD4细胞)检测,确证阳性至接受CD4细胞检测的平均时间为40天。69.0%(140/203)接受了抗病毒治疗,从HIV确证阳性至接受抗病毒治疗平均间隔为241天。CD4细胞<350个/μL、350~499个/μL、≥500个/μL组人群,接受抗病毒治疗(ART)的比例分别为80.5%(66/82)、73.0%(46/63)、44.8%(26/58)。统计学检验结果表明,CD4细胞水平与接受ART的比例间的差异有统计学意义(P<0.01)。结论 2011-2015年北京市西城区MSM的HIV报告阳性率逐年增高,其中CD4细胞≥350个/μL的病人进行ART的比例仍较低,需进一步提高基层医疗卫生机构的能力和水平。
Objective To assess the current status of MSM HIV counseling and testing services in Xicheng District, Beijing during 2011-2015. Methods A retrospective study was conducted to collect HIV testing data from 4 volunteer counseling and testing (VCT) sites in Xicheng District from 2011 to 2015. Data were analyzed and statistically analyzed by descriptive statistical analysis. Results In 2011-2015, a total of 3 487 MSM provided VCT services. HIV and syphilis were detected. HIV positive rate was 5.8% (203) and syphilis positive rate was 7.6% (265). 95.1% (193/203) of HIV-infected patients tested for CD4 ~ + T lymphocytes (CD4 cells for short), and the average time to confirm positive CD4 cell test was 40 days. 69.0% (140/203) received antiviral therapy with an average interval of 241 days from HIV-positive to antiviral therapy. The proportion of patients with CD4 <350 cells / μL, 350-499 cells / μL, ≥500 cells / μL were 80.5% (66/82), 73.0% (46/63) 44.8% (26/58). Statistical test results showed that the difference between the CD4 cell level and the proportion of receiving ART was statistically significant (P <0.01). Conclusion The HIV positive rate of MSM in Xicheng District of Beijing from 2011 to 2015 has been increasing year by year. The proportion of ART patients with CD4 cells ≥ 350 / μL is still low, which will further improve the ability and level of primary health care institutions.
